PHILADELPHIA 76ers centre Joel Embiid was unimpressed with Miami Heat forward Justice Winslow after the 22-year—old appeared to deliberately stamp on his protective eye mask during game three of their Eastern Conference playoff series last night.

Embiid made his first start in 10 games since suffering a left orbital fracture that required corrective surgery at the end of March.

The seriousness of the injury requires Embiid to wear a mask made of carbon and polycarbonate to protect the affected area with one team source telling local reporter Keith Pompey that “a forceful blow to the orbital bone could even permanently damage the sight in his left eye”.
